									CBT® 100 Resin for Flow Enhancement
CBT® 100 resin has a low melt viscosity, making it a useful additive for other plastics. The unique chemical
composition of its oligomers enables enhanced melt flow performance and uniform dispersion with minimal
effect on mechanical properties. Compatible with amorphous, semi-crystalline and crystalline resins, CBT
resin delivers improved processing performance for PC, polyester thermoplastics (PET, PBT, PCT, etc.),
nylons, acetals (POM), polyolefins, polyphenylene ethers, PVC, ABS, SAN and PMMA. Similar benefits are
observed for many blends and elastomers.

Advantages:
•   Improves the melt flow with minimal effect on
    mechanical properties
•   Achieves freedom of mold design with thinner or larger
    parts, faster cycle times, reduced residual stress, and
    less warping
•   Allows increased filler or glass loading and improved
    dispersion
•   Decreases energy consumption and enhances
    throughput
•   Reduces processing temperatures

CBT® 100 Resin in Masterbatch
Concentrates
CBT 100 resin’s low melt viscosity makes it an excellent
base resin for masterbatch concentrates. Broad
compatibility with a wide range of thermoplastics,
copolymers, elastomers, and fillers enables Cyclics
CBT 100 resin to be a versatile solution for multiple
compounding challenges. The low viscosity of the resin
promotes an extremely effective dispersion aid and
carrier.

In addition to excellent filler wet-out, the low melt
viscosity enables higher loadings with no dusting for      PC color chips using CBT color pellets
safer and easier handling. Plus, CBT resin has an
extensive shelf life at room temperature. Some of the
fillers and fiber materials compatible with CBT resin
include glass fiber and beads, carbon fiber, calcium
carbonate, wollastonite, talc, flame retardants, fumed
silica, pigments, stabilizers, and antioxidants.

Advantages:
•   Higher loadings of colorants and additives
•   Excellent dispersion                                   CBT used as carrier in               CBT used as carrier in
•   Good compatibility with a broad range of resins        masterbatch: 50wt% Nanomer®          masterbatch: 80wt% TiO2
•   Good thermal stability up to 340°C                     concentrate
•   Improved handling for powder additives
